Add slog structured logging to main controllers

[vbnrh]

• Integrated slog logging into the MirrorPeerSecretReconciler, MirrorPeerReconciler, and DRPolicyReconciler controllers.
• Improved error handling and logging for better observability and debugging.
• Replaced klog with slog for consistency across the codebase.

Changes include:

• Added Logger field to controller structs to pass and use slog.Logger.
• Enhanced logging messages to provide more context, including function names, object names, namespaces, and error details.
